There are four regulators which set standards for dental providers and can look into whether these are being met.

Care Quality Commission (CQC) regulates all primary dental care services in England - both private and NHS. The CQC cannot investigate
individual complaints, but its inspectors use information when they inspect services to make sure that they are meeting quality and safety standards.

The Regulation and Quality Improvement Authorityis Northern Ireland's independent health and social care regulator. RQIA investigates private dental care and treatment in Northern Ireland. RQIA cannot investigate individual complaints, but its inspectors use information when they inspect services to make sure that they are meeting quality and safety standards.

Healthcare Improvement Scotland(HIS) has responsibility for the regulation of independent healthcare services in Scotland, previously the responsibility of the Care Commission. HIS can only investigate cases of private treatment; for complaints about dental treatment provided
in an NHS setting, contact your local NHS Scotland health board.

The UK’s independent authority set up to uphold
information rights in the public interest, promoting openness by public bodies
and data privacy for individuals.​ The ICO will assist with matters such as
obtaining your dental records.
